GCL-0607 Air-Spaced Zero-Order Waveplates

The GCL-0607 series contains 15 online SKUs with quarter-wave or half-wave retardance and a model-specific nominal wavelength. Source cards identify the applicable value from 355, 532, 632.8, 780, 800, 808, 980 or 1064 nm. Each description follows its own card rather than decoding the model suffix or combining separate wavelengths into a broadband performance claim. The series states φ25.4 without a dimension unit or a diameter definition. Choose the retardance, intended wavelength and mechanical requirements together, then confirm accuracy and mounting details before ordering. English artwork follows the black circular housing and central optic in the source photographs. It is a family reference, not an exact engineering drawing or a fast-axis calibration record.

Retardance and wavelength by model

The 15 online models include quarter-wave (λ/4) and half-wave (λ/2) configurations. Each SKU description retains the wavelength printed on its own source card, in nm. This is a single nominal wavelength, not a continuous operating range or a bandwidth guarantee. Model suffixes are not decoded into additional specifications.

Air-spaced zero-order configuration

The source explicitly identifies air-spaced zero-order waveplates. Select the retardance, wavelength and mechanical dimensions together; a matching appearance or wavelength does not make quarter-wave and half-wave versions interchangeable. Crystal material, internal plate count, air-gap spacing, retardance accuracy and temperature response are not specified.

Dimensions and fast-axis marking

The title and cards state φ25.4 without a dimension unit or a definition of outside diameter, optic diameter or clear aperture. The value is retained for confirmation. Photography shows a black round housing, a central optic and a Fast marking. The line does not establish an alignment tolerance or axis calibration certificate. Housing thickness and mounting interfaces are absent.

Supply and performance checks

The source offers custom sizes, which does not establish additional stocked SKUs. Confirm coatings, transmission, surface quality, damage conditions, clamping, accessories and package quantity. Photographic color is not evidence of coating or wavelength suitability. English artwork is a family illustration. The source lists 2–7 days for dispatch; confirm current stock, delivery and custom-order terms.
